Abstract
The invention relates to a method for adjusting the feed opening of segments for continuous casting systems, especially position-controlled segments for slab and thin-slab continuous casting systems which comprise a strand guide (1) with segments (2) for a predetermined guidance of a cast strand using measuring and control signals. In order to provide an independent intelligent segment, the measuring and control signals are processed in at least one system unit (14) directly on the respective segment (2) and the set values are fed to the segment (2) by a superordinate control system (10) via a field bus (11), for example a profibus and a power supply (12). Actual values are returned to the control system (10) via the field bus (11) as the result of control or as a process status. The system units (14) present on the segment (2) are supplied with segment-specific data such as rigidity coefficients, roller diameter, control parameters, feed opening basic settings and adjustment quota. The invention also relates to a device for carrying out the method.
Claims (7)
1. Device for automatically controlling the feed opening of segments for continuous casting plants, which are designed at least with a position sensor (7) and a pressure sensor (8), especially for automatically controlling the feed opening of segments for slab and thin-slab continuous casting plants, which comprise a strand guide (1) with segments (2) for predetermined guidance of a cast strand with the use of measuring signals and automatic control signals, characterized by the fact that each segment (2) has at least one decentralized system unit (14), which is connected via a field bus or profi bus (11) with an overriding control system (10) and a power supply (12).
2. Device in accordance with Claim 1, characterized by the fact that the lines for bus links (11) and for the power supply (12) are equipped with plug connections for the purpose of making segment changes.
3. Device in accordance with Claim 1 or Claim 2, characterized by the fact that the system units (14) are automatic control and regulation units.
4. Device in accordance with one or more of Claims 1 to 3, characterized by the fact that the system units (14) are so-called intelligent terminals.
5. Use of the device for automatically controlling the feed opening of segments for continuous casting plants, especially segments for slab and thin-slab continuous casting plants, in accordance with Claims 1 to 4, characterized by the fact that the measuring and automatic control signals are processed in at least one system unit (14) directly on the given segment (2), the predetermined set point values are fed to the segment (2) by an overriding control system (10) via a field bus (11), e.g., a profi bus, and a power supply (12), and actual values are returned to the control system (10), likewise via the field bus (11), as control results or as the process status.
6. Use of the device in accordance with Claim 5, characterized by the fact that segment-specific data, such as modulus of elasticity in shear, roller diameter, automatic controller parameters, basic settings of the feed opening, and adjustment ratios, are supplied to the system units (14) located on the segment (2).
7. Use of the device in accordance with Claim 5 or Claim 6, characterized by the fact that, besides the necessary function(s) for accomplishing the segment adjustment, the decentralized system unit (14) is assigned additional decentralized segment-specific functions, such as acquisition and processing of other measurement data, e.g., bearing force monitoring, temperature measurements and controls, calibration data, or the like.
